How to Change Image DPI on iPhone

iPhone photos export at 72 DPI by default. Print services that auto-reject low DPI will reject them. Here’s how to change DPI without a computer.

Check current DPI on iPhone

  1. Open the photo in the Photos app.
  2. Tap the “i” (info) icon at the bottom.
  3. Look for camera metadata — size in pixels and DPI appear here.

For deeper EXIF inspection, upload to our DPI Checker via Safari.

Change DPI directly from the iPhone browser

  1. Open Safari and visit our DPI Converter.
  2. Tap the upload box → Photo Library → pick the image.
  3. Choose 300 DPI.
  4. Tap Convert → Download — the file lands in your Downloads folder.
  5. Move it back into Photos via the Files app.

If you shoot HEIC

iPhones save HEIC by default. Most online services prefer JPEG. Open Settings → Camera → Formats → Most Compatible to switch to JPEG, or convert HEIC files via our Image Converter before DPI tagging.

Print-quality sanity checks

  • iPhone 15 Pro 24 MP — safe to 16×20″ at 300 DPI.
  • iPhone 14 12 MP — safe to 13×10″ at 300 DPI.
  • Photos shot in low light may print soft regardless of DPI — check at 100% zoom.
